Research On Power Geographic Information System Based On Web Technology

The Power Geography Information System is a kind of synthetic science and technology. It makes use of a Geography Information System Technology to realize the power network's normal activities, such as safe running, maintenance, management and operation. Most of the traditional Power Geography Information System adopts low-class distributed structure which is based on the share of files, so the cost is very high and the operation is very complicated. For this purpose, this paper addresses a solution program of Power Geography Information System based on the Web technology. This program adopts the theory of three-tiered structure to frame the system and uses Oracle Spatial to restore information data. It focuses on the method of modeling spatial data of Power Geography Information System. Finally, the WebGIS system of Power Supplying Company in Xian town is developed by utilizing the software product and made into circulation. The practice result indicates that the Power Geography Information System based on Web technology has the advantages of reducing cost on a large scale, operating briefly, and making full use of system resources. Therefore, it obtains high praise of relative sectors.
